A lot of people have said that the "symbol" in G5 looks familiar. Even to me.

Now, according to Claude, we can pretty much rule out it being "part" of a langauge, meaning, it wasn't used as a writen letter. But, many langauges use symbols to represent things.

I keep thinking that it looks like some old alchemy symbol, but I haven't been able to place it. Some one suggested that it looked like a poorly drawn symbol for Saturn. The only other things that pops in my head is some sort of runic symbol.
